    Of several programming languages for IBM SYSTEM/360, the Assembler Language (AL) is closest to the machine language in form and content.1–3 Because AL enables the programmer to use all SYSTEM/360 facilities as directly as if he were coding in machine language, AL can be used for all types of applications, and affords the programmer complete freedom in adapting special programming...

    One of the basic limitations of a digital computer is the size of its available memory.1 In most cases, it is neither feasible nor economical for a user to insist that every problem program fit into memory. The number of words of information in a program often exceeds the number of cells (i.e., word locations) in memory. The only way to solve this problem is to assign more than one prog...

    With the availability of continually increasing amounts of core storage, one might reasonably expect a trend toward programs which take advantage of large tables to reduce execution times. Examples of areas in which large tables have already been found necessary for the attainment of reasonable computation times are: large-scale weather forecasting, neutron transport and diffusion calculations, an...

    Of late, considerable attention has been given to time-sharing computer systems. To provide a close relationship between the computer and its users, these systems typically handle a variety of remote terminals, from typewriters to computer graphic display systems. Although many source terminals may employ the computer concurrently, the objective is to provide a form of terminal service that makes ... View full abstract»
